Air-powered water heater
One of the biggest energy guzzlers in many homes is the water heater. With an average family of four, daily showers and household chores can deplete the contents of a fifty gallon water heater in no time, resulting in high utility bills. If you’re looking for a greener, more energy efficient water heater, here’s a green alternative that may work for your household. AirGenerate’s AirTap™ water heater uses mostly air and a small amount of electricity to heat the water. The unit attaches atop any standard electric or gas water heater and acts as a heat pump to pull the heat from the surrounding air, compress it, and send it into your water heater to heat the water inside. According to AirGenerate, their AirTap™ heat pump water heater uses 2.5 times less energy than standard water heaters. Along with energy efficient water heaters and other household appliances, don’t forget one of the simplest steps in conserving energy and water—taking shorter showers!

The AirTap A7 has been installed 8 days in my home in Phoenix. I paired it with a new Marathon super-efficient 50-gallon electric water heater. I have the two water heater elements set at 100 degrees and the AirTap is set to 115 degrees. The AirTap has run a total of 1 minute in the last week. After it ran for a couple of hours when first installed to bring the new water up to temperature, it has run only 1 minute in the last 7 days. In that time I have run 3 full dishwasher loads and have washed two “warm water” loads of clothes.It ran 14 minutes last Monday morning when I intentionally drained hot water out of the Marathon tank because I was concerned that the AirTap had not come on for the first 36 hours after it was installed. I thought there might have been some kind of problem.Instead, what was happening was that the Marathon was doing such a good job of keeping the water hot that the AirTap did not need to come on at
all.It appears the most effective combination to keep your water hot and heated with the minimal amount of electricity is to combine a Marathon water heater and an AirTap A7.I will find out this winter, when I will use a lot more hot water, how much the system REALLY can save me. I chose this combination instead of a solar water heating system. This is a great product. I will update you again in the winter. Larry S. Singleton
I too have a 50 gal Marathon, but have hesitated to put the AirTap A7 on it for fear of damaging the polybutene tank. So it was good to know someone has done this. I am also hesitating because of potential noise from the A7. Also, did it mount to the top of the 50 gal Marathon as it the photos of flat top water heaters? Larry, I will look forward to your Winter update.
